The Sealy Cocoon Chill Mattress has a beautiful and innovative cooling cover, it’s made in the USA, and you’ve got the option of all foam or hybrid construction. You get all this for a VERY budget friendly price point, but how does it compare to other “cooling” memory foam mattresses? I investigate whether the Sealy Cocoon Chill is a good buy or just a gimmick.

In this Sealy Cocoon Chill Mattress overview, I’ll take you through:

  • Features Of The Sealy Cocoon Chill Mattress
  • Detailed Look At The Special Features Of The Sealy Cocoon Chill
  • Comparison With Other Cooling Memory Foam Mattresses
  • Final Summary: Is The Sealy Cocoon Chill Mattress A Good Buy?

Sealy Cocoon Chill Mattress Features

I’ve added my opinion on each of the features to help you understand if they’re any good or just marketing hype.

  • Trial & Warranty: 100 night trial, free shipping, 10 year warranty (these are the industry standard)
  • Firmness: 6 out of 10 for firmness. This is actually my favorite firmness level because it’s the most universally comfortable. It’s the level where you can expect excellent contouring pressure relief for your hips and shoulders, but without sinking too far in.
  • Designed and made in USA: If you’re wanting to support local, this is a nice touch, especially at this price point where dozens of the competing mattresses are made overseas.
  • Cover: This is one of the main selling points of the mattress because it’s not your standard cotton stretch knit. Instead, what you get here is stretch knit that has phase change material knitted into the weave. What this means is that the cover can absorb body heat and send it away from the mattress. It’s actually a technology originally developed by NASA and is now a luxury touch in furniture items. The phase change material means the mattress will actually feel cold to touch!
  • Comfort Layers: 2 layers of memory foam. The top layer is “perfect fit” which contours and cushions, the second layer is “responsive comfort”, which acts as a support layer to stop you sinking too deep into the foams and also a transition between the softer foam above and the firmer high density support core. These types of foams are pretty common in memory foam mattresses, I’m a little bit surprised to not see any gel infusion or other cooling tech in the top layer to further enhance the cooling potential of the mattress.
  • Support Core: High density support foam in the standard Cocoon Chill mattress, individually wrapped pocket coils in the hybrid model
  • Also available as a hybrid, with coils instead of foam base. this will allow for better air circulation
  • Mattress Height: 10″ for the all foam (this is standard for a 3 foam layer mattress), 12″ for the hybrid mattress (again, pretty standard).
  • Price: $769 – $1539 for the all foam Cocoon mattress, $1139 – $1999 for the hybrid mattress with the coils.

Detailed Look At The Cooling Ability Of The Sealy Cocoon Chill

There’s really only one cooling feature in this mattress, and that’s in the cover.

The cover is infused with phase change material, which as I said earlier, was invented by NASA to absorb and dissipate body heat. This means the closest part of the mattress to your body is working very hard to keep you at a comfortable temperature (watch the video below for more info on exactly how phase change works).

This cover will actually feel cold to the touch, but don’t worry, you won’t feel cold in your bed! As you lie on the mattress, it naturally adapts to your body heat and pretty soon feels like a neutral temperature for your comfort.

I do find it interesting, and perhaps a bit lacking, that the Cocoon Chill does not have any cooling innovations in the memory foams, such as open cell for ventilation, or gel infusion to work even harder at drawing out excess body heat. I think that, given the incredibly affordable price of this mattress, Sealy have poured their costs into the phase change fabric and keeping manufacturing in the USA.

The hybrid model with the coil support core will naturally be better at cooling than the all foam model because air will flow around the coils, but the hybrid is not as good value as the memory foam.

Final Summary: Is The Sealy Cocoon Chill Mattress A Good Buy?

I think that for the price, this is a reasonable mattress anyway. You’ll find a bunch of similar mattresses at this price point without any special features that aren’t made in the USA.

I actually think that the Molecule 1 is the best value cooling mattress you’ll find, and it would be my first choice, but that doesn’t make Sealy a bad mattress to buy.

With the brand name familiarity (Sealy has been making beds for more than 100 years) and the unique point of the phase change material, I think this is a good buy. Sure, it may not be the BEST or MOST cooling mattress you could ever buy, but you’ll have a hard time finding one for such a low price.
